description of Dinochloa andamanica thus: "Specimina ex insulis Philip- 

 pinis, valvula interiore ciliata gaudentia et a cl. Munro cum D. Tjang- 

 korreh conjuncta mihi est species nova et etsi earn non vidi D. ciliatam 

 nomino;" Camus adds a figure of it. The Bornean specimens, while 

 not quite identical with Philippine material, differ less from the type 

 specimens of D. ciliata Kurz and D. scandens var. angustifolia Merr., 

 than does other Philippine material placed here. The last two are un- 

 questionably identical. The only other species of the genus known from 

 Borneo is typical Dinochloa scandens O. Kuntze, represented by Hose 65. 



PAN I CUM Linnaeus 



PANICUM BARBINODE Trin. in Mem. Acad. Petersb. VI 3 J (1835) 256. 



Sandakan, Drs. F. <fe C. Baker, January, 1915. 



This species, apparently purposely introduced for forage purposes, has 

 not previously been reported from Borneo. It is very frequently confused 

 with Panicum molle Sw. Commonly known as Para grass. 



PANICUM PERAKENSE (Hook f.) comb. nov. 



Panicum humidorum Ham. var. perakense Hook f. Fl. Brit. Ind. 7 

 (1897) 54; Ridl. Mat. Fl. Malay. Penins. (Monocot.) 3 (1907) 

 137. 



In describing this form originally Hooker states "Probably a different 

 species," i. e., distinct from P. humidorum Ham. This I am convinced 

 is the case, and accordingly I have rased the variety perakense to specific 

 rank. I have specimens from Perak, Ridley US 86; from Johor, Ridley 

 11007; and the Bornean specimen cited below. 



Sarawak, Mount Sudan, Native collector 2048 (Bur. Sci.). The species 

 is new to Borneo. 



PANICUM MALABARICUM (Linn.) Merr. in Philip. Journ. Sci. 4 (1910) 

 Bot. 248. 



Poa malabarica Linn. Sp. PL (1753) 69. 



Panicum arnottianum Nees in Steud. Syn. PI. Gram. (1854) 59. 

 Borneo, Tambusan, Ridley 12328; Mount Sudan, Native collector 20U7 

 (Bur. Sci.), the latter with prominently ciliate sheaths. 



This species has been sunk in Panicum nodosum Kunth by some authors, 

 but I consider it specifically distinct. For discussion see Merrill in 

 Philip. Journ. Sci. 4 (1910) Bot. 248. 



SPHAEROCARYUM Nees 



SPHAEROCARYUM PULCHELLUM (Roth) comb. nov. 

 Isachne pulchella Roth Nov. Sp. (1821) 58. 

 Panicum pulchellum Spreng. Syst. 1 (1825) 322. 

 Panicum malaccense Trin. Gram. Pan. (1826) 204. 

 Sphaerocaryum elegans Nees ex Steud. Nomencl. ed. 2, 2 (1841) 620. 

 Borneo, Kuching, Ridley USUI. 



The species is new to Borneo. India and Ceylon to the Malay Peninsula, 

 Singapore, and southern China.
